Nice progress on the texture so far. But the dog is a real chicken, the tail between his legs!
I would also give the entire folder of the book the same color. Silly tiny crit, but it looks like the pages blends together with the folder when the inside got pretty much same color as the pages. Aswell, it would be nice if you could get rid of the texture stretch on the ground, thats the first thing I saw.
About the pose, it would be nice if both the dog and the boy were actually looking at the same thing, or at least if they would seem a bit more teamed up. Right now the boy is thinking about algorithms while the dog is about to attack the camera. Besides that, the pose is perfect.
Is that the next edition of d’artist he is holding btw:) ?
Jokes aside, great work!
